No guarantees on this answer but this is what I would do.
That's a pretty heavy cabinet, but if you and 3 buddies stand together in
your living room, the floor doesn't collapse. But wood can settle over
time. In my living room there is a noticeable depression where the stone
fireplace lintel (maybe 400 lbs) was set on the floor while the house was
So, I'd make some wood blocks, maybe 2" x 2" or 3" by 3" and put them under
each leveling leg to spread the load. Put the cabinet against the wall so
the feet are between the joists. Then, in the crawlspace, build two columns
out of concrete blocks and wood shims (put them in tight) under the floor
where the two front legs are located. You can get wide hardwood shims from
a mobile home supply company.

Your floor should be fine:
Structural strength : If you think about it in another way, would you
be concerned if 4 large(ish) people were to stand close together on the
area of floor that you intend to put the cabinet?
Surface strength : Prefinished hardwood floors are usually finished
with an epoxy which will easily take the pressure you describe, the
underlying hardwood itself should also have no problems as they
typically have no problems supporting high heel shoes. High heels often
have areas of less than 1/4 square inch, assuming only half a persons
weight is on each heel, pressures in excess of 300lbs per square inch
only requires 150lb person.
I hope this helps.

The floor joists of the crawl space are what dimension and what spacing?
When placing a load against a wall where floor joists below bear on
structural support such as a load bearing basement wall the floor and joists
themselves may support the weight when using 2x10 floor joists 16" OC but to
be especially secure you canand probably should consider bracing by using a
4x4 double T brace ( TT ) underside of the floor joists to carry the extra
loads down to the slab or soil below. You see the way the T illustrates a
brace and two columns? If there is soil under the crawl space stack a couple
of leveled concrete patio blocks onto the surface of the soil to function as
a pad the columns bear on. Use 4x4 for the brace and columns. It wouldn't
hurt to ask a building inspector for advice either.
